Laptops

I think what is meant is that some laptop PSU's come with a plug with a grounding pin, that will not fit in outlets, that are not grounded. Then you need an adaptor. --elgaard 13:52, 1 Feb 2005 (EST)

Still, seems weird. Have you seen a laptop PSU like this, where one could not simply replace the connecting cable with the plug ? Aren't we inventing things here ? Wojsyl 17:30, 1 Feb 2005 (EST)

I would have thought so until I got my new Dell, which indeed has a 3-pronged plug, connected to the PSU with a weird-ass proprietary cable. So evidently these exist. Jpatokal 22:23, 1 Feb 2005 (EST)

They certaily do. I am traveling now and had to go to K-mart and buy a 3->2 plug adapter so I would not have to use my laptop in the bathroom (which have grounded plugs). Danish grounded plugs also have a pin, and can need an adapter. Of course you could cut off the plug and mount a two-pin plug. But you might prefer to ground it when you can, or you employer do not approve , etc. --elgaard 04:34, 2 Feb 2005 (EST)

Italy

The italien diagram is misleading. The holes have a smaller diameter, which mean they cannot be used with all plugs that would work in the "continental Europe" outlets. --elgaard 22:48, 31 Jul 2005 (EDT)

Israel

The Israel diagram is also misleading. In 90 % of israel sockets, the two holes have semi-circular form, alowing them to be used with the "continental Europe" outlets. --jarondl 15:19, 2 Oct 2006 (IST)

hairdryer

That thing about testing voltage using a hairdryer, is that correct? I'd guess that if the engine spins fast despite being set to "Slow", this means it's fed 240V while set to 120V, not the other way around. Problem is, I'm easily confused so I thought I'd check here first before editing ;) {Peirz 23:02, 11 April 2007 (EDT)}

I have edited that section out. It could work if you know what you are doing, but would be dangerous if you make a mistake. Davidbstanley 03:23, 12 April 2007 (EDT)
